Have you ever wondered how dirty your house really is? I decided to try a little mold science experiment with my kids and see what things we need to do better at cleaning. I was quite surprised by the results. The kids and I had fun with this one, but is honestly gross to think about the amount of germs on the things we touch all of the time.
Make the gelatin first. Boil 2 cups of water and prepare the gelatin. Stir it until it dissolves. Then pour it into your containers. Make sure these are clean and not contaminated already. You don’t need much in each container. We used six different ones and just divided it evenly. Then let the gelatin set up. I waited a day before getting back to it.
The next day, we got q-tips wet and rubbed them on different surfaces throughout the house. We swabbed the trash can lid, the stove burner, the bathroom cabinet handle, one of my kid’s hands, the kitchen counter
After swabbing these different areas, label each cup and rub the q-tip all over the gelatin in the cup. Cover them securely and set in a dark place for a time. After a few days (even after just one day) mold will start to grow on the surfaces. We kept them growing for about a week to really see a large amount of mold.
We guessed ahead of time which areas we thought would be the dirtiest and grow the most mold. I was dead wrong… I thought for sure that the trash can lid would be the worst, but from the results it seems my stove needs a good scrubbing!!!
Have you ever tried the mold science experiment before? Try it out in your house and see what results you get… you may be unpleasantly surprised.
